POST method doesn't working

[miladr]

I'm using this code to send a POST request but it's not working.

<?php

require 'vendor/autoload.php';

$loop = React\EventLoop\Factory::create();

$dnsResolverFactory = new React\Dns\Resolver\Factory();
$dnsResolver = $dnsResolverFactory->createCached('8.8.8.8', $loop);

$factory = new React\HttpClient\Factory();
$client = $factory->create($loop, $dnsResolver);

$request = $client->request('POST', 'http://respondto.it/bomber');

$request->write("test=12345");

$request->on(
    'response',
    function ($response) {
        echo "recived".PHP_EOL;
        $response->on(
            'data',
            function ($data) {
                var_dump($data);
            }
        );
    }
);
$request->end();
$loop->run();

Result is

POST /bomber
Headers

Connect-Time: 1

I know that i'm doing something wrong but i couldn't find solution.

Would you care to elaborate on what "but it's not working" refers to? :)

Sending HTTP requests which include a body (such as your POST) requires the client to tell the server the expected length either via the Content-Length header or via chunked transfer encoding (which is currently not supported). Also, the data you're sending appears to be formatted like HTML form data, so you need to specify the correct Content-Type header like so:

$data = 'test=12345';
$request = $client->request(
    'POST',
    'http://respondto.it/bomber',
    array(
        'Content-Length' => strlen($data),
        'Content-Type' => 'application/x-www-form-urlencoded'
    )
);
$request->end($data);

As you can see in result, body wasn't received.
But it was my mistake. I forgot to add headers because i expected that Client will add necessary Headers. I suggest to add this to documentation.
Thank you.
